Abstract

Release coated nonwoven sheet materials are provided through the process of (a) forming a web from fibers; (b) applying a water-based binder to the web; (c) applying a water-based release coating to one side of said web while the web is still wet from the application of the binder;
and (d) drying said web. This process eliminates at least one heating step, with unexpected control of the migration of the release coating through the web.
